Cadent is exploring transitioning from coefficient-based methane reporting towards a measurement-informed approach using vehicle-based advanced leak detection (ALD) data. The process has been developed using the Verias Distribution Source-Level Protocols and is intended to support compliance with applicable Oil and Gas Methane Partnership (OGMP 2.0) Level 5 requirements for the sources within scope. This RFI aims to understand the capability, experience, methodologies and assurance approach available from organisations capable of providing an independent opinion on conformance with Veritas and OGMP 2.0 requirements. Suppliers should clearly state any assumptions regarding scope, maturity of the process, and assurance standards applied. Please Note: This RFI is for information only and does not constitute a commitment to procure.
